During March 2001, 117 working mules, randomly chosen from four markets in Morocco, were weighed and a series of body measurements recorded; their age and body condition score were also recorded. Linear regression techniques were used to derive a 'best fit' equation for predicting liveweight from the other variables. For the working mules weighing between 131 and 391 kg the best prediction equation using two variables was: liveweight (kg) = -33 + 2.8 x heart girth (cm)+1.36 x length (cm). Other prediction equations available for estimating the liveweight of equidae were tested on the data, but in all cases they significantly overestimated the weights of the Moroccan mules.

Summary This report describes a case of a non‐lethal tetanus in a donkey that re‐presented 9 months after discharge with a second episode of tetanus. This is the first time “recurrent” tetanus has been reported in equids, although it is a recognised, albeit rare occurrence in humans. This case illustrates the fact that natural infection did not confer immunity in this particular donkey. This highlights the importance of tetanus toxoid vaccination even for animals that recover from the disease.

SummaryAn 8‐year‐old bay mule was presented with moderate right forelimb lameness and dark discolouration of the white line. Histopathology of the dark material indicated a melanoma. Extensive resection and debridement were not curative and the mule was subjected to euthanasia 70 days after presentation.
